Build an autonomous agent that reads large-scale numerical datasets from my finance stack—trading logs, ledger exports, and KPI spreadsheets—and turns them into clear, actionable insights. The workflow I have in mind is: • Securely import CSV or database streams, then validate and cleanse the figures • Run statistical profiling, anomaly detection, and predictive modeling (Python, pandas, scikit-learn, or similar) • Present results through concise dashboards or an API endpoint so the rest of the team can query forecasts and risk flags on demand Well-structured, well-commented code and a brief usage guide are essential. Final delivery will be a self-contained repo (Docker image preferred) plus a sample report generated from the provided test data so I can confirm accuracy before we hook it into production.

The world is currently on track for ~2.5°C of warming, which would have catastrophic consequences for societies, ecosystems, and economies. Three realities define the challenge: 1. We are burning millions of years of stored carbon in a single human lifetime. The only viable path forward is rapid global decarbonisation. 2. Decarbonisation is complex and politically sensitive: Cost-of-living pressures, geopolitical conflict, and unequal responsibilities make coordinated action difficult. 3. Nevertheless, this is humanity’s defining survival challenge. We must rapidly understand — and then reduce — the emissions embedded in everything we produce and consume. There is some good news: Power grids are decarbonising quickly and electrification is accelerating across transport and building systems. However, most of the emissions that remain are embedded in physical goods — the energy used to extract raw materials, move them across the planet, and transform them into the chemicals, metals, plastics, fibres, and components that form modern life.   Our mission is to model the raw material world from well and field to factory gate and enable the manufacturing economy to make healthier decisions for their companies and our planet. We are looking for an analyst to support the COO and co-founder for an initial 3 month period in developing the intellectual framework of our next generation model. Specifically this role will involve: * Codifying specific models (for example a “feedstock pricing model for naphtha”) and working with the Engineering team to support its coding and deployment * Leading on model documentation and internal understanding * Identifying and testing third party data sources (for example, grid carbon intensity data) and onboarding new feeds * Leading a team of data analysts working on entity matching and entity enrichment We invite any candidates with the following experience to apply: * Either of: * A ChemEng (or equivalent) academic background and an understanding of the basics of industrial chemistry * A Supply Chain / Trade Data background with specific experience in raw material procurement * 5+ years commercial experience (with an allowance made for PhD level academic qualifications) * Proven experience in building commercially-driven analytical models (whether in industry, finance, consulting or data science contexts) Everyone at Atmospheric AI must be great at: * Working with ambiguity and creating order from chaos * Showing deep agency and personal responsibility * Moving extremely fast to tackle serious challenges This is a full time role (we will consider candidates who can offer at least 30 hours a week) for an initial 3 months, remote based with the potential to work from our offices in London or Lisbon (we operate on UK time zones) and will pay $30-40/hour depending on experience. There is the potential for this project to be extended or to turn into a permanent position. Client's questions: Please give an overview of your experience in industrial chemicals and/or raw material supply chains. Please give an overview of your experience building analytical models (in excel or code). Please explain how you would fit into a high-paced, constantly evolving start up world supporting at the very most senior levels of the company Hourly rate: 30 - 40 USD 4 hours ago Client's recent history (5 works) Jobs in progress (1) Expert Petrochemical Data Scraper for Global Polymer Grades (JSON Output) Oct 2025 - Present 9 hrs @ $44.31/hr Billed: $398.75 View more (-4) Scraping ISCC No feedback given Nov 2025 21 hrs @ $43.67/hr Billed: $917.11 Expert Petrochemical Data Scraper for Global Polymer Grades (JSON Output) To freelancer: 5 To client: 5 We had a great experience working with Roee Goldberg.

The Mission We are building a fully autonomous, high-frequency quantitative trading ecosystem inspired by the RenTech/Jim Simons approach. We are moving beyond simple technical analysis to build a "Multi-Agent" system that fuses hard market data with unstructured "soft" data (social sentiment, research papers, alpha groups) to identify non-intuitive market patterns. We are looking for a 0-to-1 builder capable of architecting the entire pipeline from data ingestion to execution. Here are two versions of the job post, depending on how you want to hire. Option 1 is for a "Founding Engineer" type—someone you want to partner with or hire long-term to own the whole system. Option 2 is for a Freelancer/Contractor—best if you want to build this stage-by-stage with clear deliverables. Option 1: The "Visionary" Post (Best for long-term/full-stack ownership) Job Title: Lead AI Quant Architect (Python/ML) – Building "Medallion 2.0" The Mission We are building a fully autonomous, high-frequency quantitative trading ecosystem inspired by the RenTech/Jim Simons approach. We are moving beyond simple technical analysis to build a "Multi-Agent" system that fuses hard market data with unstructured "soft" data (social sentiment, research papers, alpha groups) to identify non-intuitive market patterns. We are looking for a 0-to-1 builder capable of architecting the entire pipeline from data ingestion to execution. What You Will Build (The Architecture) 1. The Omni-Data Engine: A robust ingestion pipeline that normalizes distinct data sets—from Real-time Open Interest and On-Chain data to unstructured text from Twitter, YouTube transcripts, and PDF research papers. 2. The Strategy Core: An AI-driven engine that synthesizes these inputs (e.g., "Sentiment is High" + "Funding is Low") into executable trade signals. 3. The Simulation Lab: A Python-based backtesting environment that accounts for slippage, fees, and market impact, capable of running parameter grids (rolling windows, z-scores) to optimize performance. 4. The "Feedback Loop": A self-correcting mechanism that tracks source accuracy (scoring alpha sources) and auto-tunes strategy parameters based on real-world outcomes. The Tech Stack - Core: Python (Pandas, NumPy). - Backtesting: Custom build or frameworks like Backtrader/Lean. - AI/NLP: LLMs (OpenAI/Claude APIs or local Llama) for sentiment analysis and pattern recognition. - Data: Experience handling Time-Series data and JSON/NoSQL databases.

QuantConnect SMA Intraday momentum Bot (python)	~166 - 497 USD	11 hours ago	Client Rank - Medium Payment method verified 1 open job no reviews Registered: Dec 5, 2025 Australia 3
I need a high-performance momentum-based trading system built inside QuantConnect’s Lean engine using Python. The strategy already has a defined logic it focuses on short-term intraday momentum signals with dynamic stacking and capital reallocation. The system should: • Run fully within QuantConnect, using its native data and order-handling framework. • Trade U.S. and high-volume global equities (Europe, Asia, Australia) universe should be modular. • Use technical indicators (EMA crossovers, RSI, MACD, ADX, ATR, volume spikes) for entry logic. • Implement dynamic stacking, add to winning positions every +1× ATR above last entry. • Use a shared trailing stop for each stacked group, updating dynamically as price rises. • Include a capital rotation system: pull capital from underperforming positions and reallocate to higher-momentum assets. • Run on short timeframes (e.g., 1,3,5,10, 15-minute candles) with adjustable parameters so i can test and decide myself. • Log all trades, capital changes, and performance metrics clearly. Deliverables I expect: A well-commented Python algorithm file ready to drop into my QuantConnect project (fully compatible with Lean). A backtest covering at least three years (preferably December 2022) with detailed performance metrics: total return, drawdown, win rate, and trade log. Clear in-code parameters for all tunable elements (EMA periods, RSI length, ATR multiplier, stacking distance, stop-loss aggressiveness, capital rotation intervals). A short read-me explaining how to adjust those parameters and rerun backtests. Additional Notes: • The system should not use margin or leverage only cash capital. • It should be designed to scale smoothly to higher capital levels. • Code must compile and run successfully in QuantConnect’s cloud environment before delivery. • Machine learning integration is a plus. NB: The price quoted is what will be agreed upon.

They kept asking me to "copy off the website" when I requested high-resolution images. I had to ask for a logo, ask for product images, ask for fonts, etc. They also continued to request free work after I had already given them very deep discounts. Additionally, I was hired to manage LinkedIn posting and ads, but then they decided to deny me access and create a separate account. Thus, I was not able to gauge metrics or tweak ads, yet they still wanted to hold me accountable for the numbers. I also explained that I am on a US time schedule of 9-5 pm, M-F Central, and they kept demanding that I meet with them at 10, 11, and 12:00 at night. They did not seem to respect my time at all.

He says that he have more work for me so he say that he'll not end this contract and give me more work but 20 days are gone and I've no more work from him. 5 days ago he'll contact me on Skype and told me that he have more work but first he want to a sample work from me. I'll give him sample work but he says that he will give me more work according to the sample work but now he is completely UN responsive. Whenever i'll contact him he just say that he give me more work but he don't.
